To all whom it may concern.

Be it known that I, EMANUEL FISHER, a

citizen of the United States, residing at Providence, in the county ofProvidence and State of Rhode Island, haveinvented certain new anduseful Improvements in Valves, of which the following'is aspecification.

This invention relates to improvements in the construction of multipleseated valves of. the type more particularly adapted to be I connectedin a line of pipe to control the flow of fluid. therethrough, and theobject of this invention is to provide a multiple faced, rotatablymountedvalve member in the valve casing, and having improved meanswhereby it may be positively locked inany of its several workingpositions against rotatlon and also to prov de means for releasing thelocking member when des1red and rotating the valve from one operatingposition to another, and this invention is an improvement in theconstruction of such valves over my two prior Patents Numbers1,157,641,.patented October 19, 1915, and 1,157,642, patented October19, 1915.

A further object of the invention is to guide the valve to land squarelyupon its seat and that without engaging the seat with y a rotatingaction.

With these and other objectsin view, the invention consists of certainnovel features of construction, as will be more fully described, andparticularly pointed out in the appended claims.

In the accompanying drawings:

Figure 11 is an end view of a rotatable valve member shown in Figure 10.

It is found" in practice in the construction of valves of this characterof vital importance to so lock the rotatable valve memher in its variousoperating positions in the casing that it cannot possibly be afiected tobe rotated by action of the fluid moving rapidly therethrough, and thefollowing is a detailed description of one means by which this result beaccomplished:--

With reference .to the drawigs, 10 designates the body portion of myimproved valve which may be of thattype which is adapted -to beconnected in a pipe line for controlling the flow of fluidstherethrough, the same being provided with openings 11 at either end towhich the pipe may be connected. Also this body. is provided with a seatweb or partition 12 through. which is a passageway 13, the upper face ofthis partition be ing preferablya plain surface 14: against which thevalve or closing member 15 seats.

' The upper portion ofthecasing 16 is conan enlargement rotatablyconnected to the yoke 'member 23 by a screw-threaded nut 2 L This yokemember" to which the stem is connected is 'best shown in Figure 3,

jured from use. As the sizes increase they naturally engage a freshportion or area of the seat 111 the casing thus renew ng theeffectiveness of the valve with the presenta tion of each new seat.

This valve or closure member is provided with a transverse centralopening through it and when positioned between the branches 29 and 30 ofthe yoke a pivot pin 31 is passed through this valve opening and theopenings'32 in theyoke branches, and this pivot pin is secured inposition in the valve by means of the set screw 33.

This valve member is alsoprovided with abore 34 whose axis is parallelwith that of the pivot pin and spaced slightly apart therefrom and inthis bore is mounted an endways sliding bolt 35 one end of which isreduced as at 36 to enter the four holes 37 in the yoke 23 this boltbeing pressed to enter when presented to these holes by spring 38. i

This bolt is provided with a laterally-extending finger 39 adapted toslide in slot 40 in the pivot pin 31. i 1 a In order to rotate thisvalve member and also simultaneously move the locking bolt from engagingposition, I have provided a wrench member 41 having a thin blade 42 atitsfinner end adapted to enter the slot 40 of the pivot pin.' Thiswrench is rotatably mounted in a boss 43 on-the side of the valvecasing, to extend through a packing gland and-its outer end is providedwith an operating pin 44 which passes through a squared portion 45 onwhich numbers appear, corresponding with those onthe difit'erentfaces'of the valve. member so that by looking atthewrenchthe relativepositions of theseats may be at once determined. The socket portion 46,see Figure 5,.ofthe casing in which the blade portion 42 of the wrenchis housed when in inoperative position, is of such shape as to preventthe wrench from rotating. Therefore it will be seen that as the wrenchcannot rot-ate'except with the valve its numerals mustt-rulyrindicatefthe relative position of the different seats in thevalve.

By this construction it will be seen that when'it is; desiredto rotatethe valve to move a fresh seat into operative position it is only ne eary "which engages'the ,finger "39 of the bolt,

tion it.

to force the wrench inwardly withdrawing the end of the bolt fromengagement with its hole in the yoke after which the wrench is rotatedone-quarter of a revolution to bring the seat of the next largest sizeinto operating position after which the wrench is withdrawn and the bolt35 is caused by its spring to enter the next opening 37 in the yokeagain locking the valve against rotation. This seat may be used so longas it is tight, after which the yoke with its valve is raised to itsextreme uppo s'ition, as illustrated in Figure 1, which brings its pivotpin in line with the wrench member permitting it to be again inserted torotate the valve to present another seat which is larger than the onepreviously used. This operation may be repeated until all of the seatshave been used and that ;withoutremoving the valve from the pipeline.

' After all the seats have become worn it is only necessary to removethe upper portion of the valve casing, take out the valve block, refa'ceall of the seats and replace the same, in which case the valve is readyfor further service.

By providing the keys for guiding the yoke vertically in the valvecasing I perform two important functions; first, I hold the valveagainst rotation as it is being forced against its seat, which preventswear ing, cutting or injuring the seat as the valve is forcedtherea'gainst; and second, by this guiding device 1 absolutely align theaxis ofthe pivot pin with that of the wrench so as to permit the wrenchto acurately enter the slot 40 in the pivot pm when desired.

I have shown and described a construction of valve wherein a lockingbolt is provided and is withdrawn automatically by the positioning ofthe operating key, but in some instances'I may perform this positivelooking action by the structure 'shownin- Figure 9, which is that ofproviding a set-screw 47 that may be operated by a stem 48 and is firstinserted into the valve so as not to lose its position. In other words,if the set-screw were withdrawn before the wrench 49 were positioned,the valve might be accidentally rotated on its axis out of its properworking position, in which event the casing would have to be removed toagain locate and posi- In still other cases I may provide a pawl member50 as illustrated in Figure 10, which. is pivoted at 51 in the yoke 52whereby when the yoke is raised to its uppermost position 'the tail 53ofthe pawl engages the wall 54 of the recess in the wall of the casingcausing the engaging pin portion 55 of the pawl to be withdrawn from thesocket 56 in the valve 57 thus permittin "the wrench as illustrated inFigures 1- an 9to be'inserted to rotate the valve on its pivot pin andas the yoke is again forced down the tail 58 of the pawl is caused toengage the tapered wall 59 of the casing forcing it back into theopening 56 in the valve block.

When a pawl of this character is provided the pivot pin 60 may beslotted if desired as at 61, to permit the tail of the pawl to enterwhen in operative position.

My improved valve is very practical in construction and effective in itsoperation and by its use the. life of the valve is prolonged many timesover that of the usual single seated valve.
